Electromagnetic brake Brief introduction(Dry Single-plate Solenoid Brake)
Release Date:07/12/2015
High quality electromagnetic brakes(also called electro-mechanical brakes or EM brakes) slow or stop motion using electromagnetic force to apply mechanical resistance (friction).
The original name was "electro-mechanical brakes" but over the years the name changed to "hysteresis brakes", referring to their actuation method. Since becoming popular in the mid-20th century especially in trains and trolleys, the variety of applications and brake designs has increased dramatically, but the basic operation remains the same.
Both hysteresis brakes and eddy current brakes use electromagnetic force but hysteresis brakes ultimately depend on friction and eddy current brakes use magnetic force directly.
